Kako se podjetja za darilne škatle lahko spopadejo s težavami v sezonski proizvodnji
Podjetja za darilne škatle iz papirja so proizvodno{0}}usmerjena podjetja s številnimi proizvodnimi povezavami in številnimi dejavniki, ki vplivajo na kakovost izdelkov. Te dejavnike lahko razdelimo na notranje in zunanje dejavnike, lahko pa jih razdelimo tudi na dejavnike, ki jih je mogoče nadzorovati, in dejavnike, ki jih je mogoče nadzorovati. V skladu z ustreznimi načeli upravljanja podjetja, ko pride do težave v proizvodnem procesu darilnih papirnatih škatel, je na splošno treba začeti od ljudi (osebje na proizvodnem mestu), strojev (proizvodna oprema in pripomočki), zakonov (proizvodna pravila in predpisi), materiali (proizvodni materiali) in okolje (proizvodno okolje). ) 5 glavnih dejavnikov s posebnimi raziskavami in analizami ugotoviti, kateri so neposredni vplivni dejavniki, poiskati problem, vzpostaviti popoln procesni sistem in mehanizem, pravočasno prilagoditi kontrolne parametre in zagotoviti stabilnost kakovosti izdelka.
Every time the seasons change (especially spring and summer or autumn and winter), it is the time when Gift Paper Boxes production is most prone to problems. Among these problems, the most prominent ones are excessive solvent residues, decreased printing quality, white spots in the composite link or decreased composite strength. The direct influencing factor that causes these problems is the "production environment" factor in the above five major factors, because seasonal changes will inevitably bring about changes in the environment, and the most obvious changes are changes in ambient temperature and humidity. However, if the Gift Paper Boxes production is carried out in the GMP workshop with constant temperature and humidity, it should be another matter; but for most Gift Paper Boxes enterprises in my country, the seasonal production problem of Gift Paper Boxes is still very prominent and should be paid attention to. Enterprises should list the key control parameters of each link of the production process according to the seasonal characteristics of the region, establish files after verification, and establish key control points. Next, I will share with you some actual cases of seasonal production of Gift Paper Boxes, hoping to play a role in attracting others.
Primer 1
One year, spring came relatively late, and it wasn't until the beginning of April that Chengdu felt the warmth of spring. Considering the printing effect and solvent residue control, the ink solvent used by our company in winter printing is mainly ethyl acetate, which dries faster. However, after entering mid-April, the temperature quickly warmed up, and the operators still prepared the ink solvent according to their previous habits, resulting in problems such as poor ink transfer, loss of dots, and dry printing. We then added n-propyl ester to the solvent, which slowed down the drying of the ink, and things got better.

At present, when our company produces most of the retort packaging, a certain amount of curing agent will be added to the polyurethane ink. The selected curing agent is generally isocyanate-terminated polyurethane that is very sensitive to hydroxyl (-OH). However, it should be noted that in a high-humidity environment, this curing agent will react with moisture in the air, resulting in the following effects: 1. The curing agent is consumed, and this curing agent is generally expensive, increasing the cost pressure, At the same time, it will also increase the risk of peeling strength problems; ② bubbles are generated between the composite layers, resulting in poor appearance of the composite product; ③ the reaction product is polyurea-type polyurethane with high cohesive energy, which will form spots and crystal points in the composite link; ④The hard shell of the surface layer can also prevent the volatilization of the internal solvent, resulting in an increase in the residual amount of the solvent. In addition, the high temperature also promotes the reaction rate of the curing agent with moisture in the air. After our company noticed this problem, we appointed a special person to keep and store the ink consumables, and use the prepared ink as soon as possible. The remaining ink must be stored in a cool and ventilated place. Store in a sealed container. When it is in the season of high temperature and high humidity, these measures need to be further implemented.

BOPA film is a commonly used substrate in the production of Gift Paper Boxes. Due to the existence of one NH- and one C-O= in the molecular structure of BOPA, hydrogen bonds will be formed. When water is approached, water molecules will also intervene to form molecular chains. Longer hydrogen bonds increase the flexibility and breathability of the BOPA film. Experiments have shown that when a BOPA film with a length of 100mm is placed in a high humidity environment for 10 minutes, it will grow to 110mm, with a change range of 10 percent . This feature of BOPA film is very unfavorable for production. A little carelessness will cause a phenomenon similar to the "ruffled edge" of paper, and lead to quality problems such as inaccurate overprinting, specification deviation, and compound spots. Therefore, during the seasons when the humidity changes significantly, special attention should be paid to the storage and use of BOPA film, and try to avoid placing it in a high-humidity environment. In addition, temperature is also a factor that needs special attention. BOPA film is also sensitive to changes in ambient temperature. Therefore, during storage and use, appropriate temperature parameters should be set to avoid expansion and deformation of BOPA film caused by temperature changes, and therefore Unnecessary troubles brought to normal production.

Eno leto poleti je dežja še posebej obilno, visoka je tudi temperatura, kar je tipično okolje z visoko temperaturo in visoko vlažnostjo. Avtor je ugotovil, da se je oprijem med aluminizirano plastjo in osnovnim materialom izdelkov MCPP in MPET, proizvedenih v delavnici, v tej fazi poslabšal, aluminizirana plast pa je celo neposredno odpadla. Aluminizirana plast MCPP je resneje odpadla. Razlog je v vpletenosti vodnih molekul. Polarnost PET filma je močnejša od polarnosti filma CPP, zato je film MCPP lažje
Primer 5
V procesu ekstruzijskega laminiranja mnogi operaterji pogosto zanemarijo vpliv temperature in vlažnosti okolice, kot je to storil avtor prej. Kasneje pa sem ugotovil, da ima sprememba vlažnosti zelo pomemben vpliv na trdnost kompozita ekstrudiranih kompozitnih izdelkov. Postopek pihanja filma je bolj občutljiv na temperaturo okolice. Med proizvodnjo pozimi in poleti je treba prilagoditi ustrezne parametre obdelave, temperaturna razlika pa je na splošno okoli 10 stopinj.

V procesu tiska je zelo pogosta težava kvarjenja črnila zaradi hlapljenja topil zaradi sprememb temperature in vlažnosti okolice, ta težava pa obstaja tudi pri kompozitnem postopku. Izhlapevanje topila zahteva določeno količino energije. Med postopkom izhlapevanja bo topilo v pladnju za lepilo ali lepilo na površini filma odvzelo del toplote, kar bo zmanjšalo temperaturo okoliškega zraka, zato je gumijast pladenj običajno hladen. Ko temperatura doseže točko kondenzacije vodne pare, se bo na njeni površini nabrala vlaga, in ko se lepilo med folijo in premaznim valjem loči z veliko hitrostjo pod delovanjem valja, bo vlaga izkoristila priložnost, da se vnesite ga. Avtor je opravil teste in podatki kažejo, da je vsebnost vode v na novo pripravljenem lepilu {{0}},03 odstotka , vsebnost vode pa bo po pol ure uporabe v nezatesnjenem stanju dosegla 0,46 odstotka. država. V tem času je sestavljena bela točka očitna, koloid je bel, viskoznost se poveča in ta pojav je bolj očiten v okolju visoke temperature in visoke vlažnosti.

Bilo je leto, ko je bila poletna temperatura zelo visoka, a padavin dolgo ni bilo. V okolju tako visoke temperature in nizke vlažnosti je statično elektriko, ki nastane zaradi trenja filma, težko prevesti in odstraniti z ozemljitvijo, kopičenje statične elektrike do določene mere pa ne bo pomembno vplivalo le na kakovost filma. tiskanih izdelkov, ampak tudi povzročajo električne iskre in celo povzročajo požare, kar povzroča osebno in premoženjsko škodo. Zato je treba v tem okolju posebno pozornost nameniti nadzoru in odpravljanju statične elektrike z opremo za odpravo statične elektrike in metodami nadzora vlažnosti okolja.
Če povzamemo, podjetja z darilnimi papirnatimi škatlami bi morala biti pozorna na sezonske proizvodne težave, predvsem pa paziti in nadzorovati temperaturo in vlažnost v proizvodni delavnici, namestiti instrumente za uravnavanje temperature in vlažnosti, urediti posebno osebje za spremljanje podatkov, oblikovanje zapisovnih datotek in poskusite nadzorovati temperaturo okolice na približno 24 stopinj. relativna vlažnost je nadzorovana na 60 odstotkov; ko je nepravilnost ugotovljena, jo je treba pravočasno obravnavati, prilagoditi proces, odpraviti skrite nevarnosti in zagotoviti varno proizvodnjo.
